Arduino Holder

Got tired of the mess while i was bench testing and learning new Arduino starter stuff. Things were moving around, coming unplugged, so i made this rig to hold it all in place.

Made the holder for my Muizei Ultimate Starter Kit. Works with any Arduino UNO R3. Works with ELEGOO starter kit.
Holds Arduino UNO R3, Power supply, large bread board, small bread board, 2 servos(9g Micro) , joystick, small motor controller, and step motor.

First ever upload. let me know what i can improve.
